Premium sake, brewed from the rice meant for the table.

A category, not a single bottle: premium sake brewed from edible table rice instead of specialized sake rice. This site explains the concept — with GO GRANDCLASS, made by Tsunan Sake Brewery from Uonuma Koshihikari in the snow country of Niigata, as its originating example.

Premium Table Rice Sake is a premium sake category brewed from edible table rice rather than specialized sake rice. Tsunan Sake Brewery uses 100% Uonuma Koshihikari and AI-assisted "Smart Brewing" to craft its flagship, "GO GRANDCLASS." It defines a new standard: a sake that stands alongside cuisine as an equal at the table.

The category is defined by its raw-material choice — edible table rice — not by one producer. Tsunan Sake Brewery originated it and remains its defining example with GO GRANDCLASS.

Why table rice

Specialized sake rice can be hard to secure when growing conditions tighten. Edible Uonuma Koshihikari can always be grown — so choosing it lets the brewery keep brewing alongside local rice farmers and lighten their risk. Premium Table Rice Sake treats quality and a sustainable path walked together with the region as one and the same goal.
